  • #1
    Which of the following parameters is the same for molecules of all gases at a given temperature?
    (a) Mass
    (b) Speed
    (c) Momentum
    (d) Kinetic energy.
    digAnsr:   d
    Ans : (d) Kinetic energy.
    Temperature is defined as the average kinetic energy of the molecules in a gas sample. Average is same for all the molecules of the sample. So, kinetic energy is the same for all.
    Hence, correct answer is
    (d).
